KEY MESSAGES
UPDATED AT 651 PM EST SUN FEB 1 2026
- DANGEROUSLY COLD TEMPERATURES AND APPARENT TEMPERATURES ARE
EXPECTED AGAIN TONIGHT INTO MONDAY MORNING. MEMBERS OF THE
GENERAL PUBLIC AND AGRICULTURAL INTERESTS ARE ADVISED TO
PREPARE ACCORDINGLY.
- HAZARDOUS MARINE CONDITIONS CONTINUE TODAY. MARINERS SHOULD
STAY UP TO DATE WITH THE LATEST MARINE FORECAST OVER THE
NEXT SEVERAL DAYS.
UPDATE
ISSUED AT 214 PM EST SUN FEB 1 2026
THE STRONG WINDS FROM OVERNIGHT AND THIS MORNING CONTINUE TO
DECREASE, ALTHOUGH IT REMAINS BREEZY ACROSS THE REGION THROUGH THE
REST OF TODAY. BREEZY CONDITIONS WILL CONTINUE TO CEASE TOMORROW
AS THE DEEP LOW PRESSURE IN THE WESTERN ATLANTIC CONTINUES TO
DEPART FURTHER EASTWARD.
UNTIL THIS LOW GETS FAR ENOUGH AWAY FROM THE GENERAL VICINITY,
WINDS WILL REMAIN OUT OF THE NNW AND KEEP THIS COLDER AIR MASS IN
PLACE TONIGHT THROUGH TOMORROW. LOW TEMPERATURES GOT INTO THE 30S
ALONG THE COASTAL AREAS AND METRO AREAS, WITH TEMPERATURES IN THE
20S CLOSER TO THE LAKE O AREA. THIS IS EXPECTED TO HAPPEN AGAIN
TONIGHT, ALTHOUGH COASTAL LOCATIONS MIGHT PERHAPS BE A COUPLE OF
DEGREES WARMER.
WITH COLD TEMPERATURES EXPECTED AGAIN TONIGHT, A COLD WEATHER
ADVISORY HAS BEEN ISSUED AGAIN FOR THE ENTIRE REGION TONIGHT UNTIL
10AM MONDAY. ADDITIONALLY, A FREEZE WARNING HAS BEEN ISSUED FOR
TONIGHT UNTIL 9AM MONDAY FOR INLAND LOCATIONS. THE METRO LOCATIONS
ARE NOT INCLUDED IN THE FREEZE WARNING FOR TONIGHT. ANY FURTHER
UPDATES TO THE FORECAST WILL CONTINUE TO BE COMMUNICATED, BUT IN
GENERAL IT WILL BE ANOTHER ANOMALOUSLY COLD NIGHT TONIGHT ACROSS
SOUTH FLORIDA.
SHORT TERM
(TODAY THROUGH MONDAY)
ISSUED AT 106 AM EST SUN FEB 1 2026
STRONG COLD FRONT HAS CROSSED SOUTH FL AND ONE OF THE COLDEST
AIRMASSES SOUTH FL HAS EXPERIENCED SINCE AT LEAST 2010 IS FILTERING
INTO THE REGION EARLY THIS MORNING. THE BACK-TRAJECTORY OF THIS
AIRMASS CAN BE TRACED BACK TO HUDSON BAY IN CANADA. LATEST ACARS
SOUNDING FOR MIA SHOWS A PWAT VALUE OF 0.5 INCHES, AND GUIDANCE
SUGGESTS THAT SHOULD DROP FURTHER TO AROUND 0.2 INCHES BY DAYBREAK.
THE 540 THICKNESS LINE IS ALL THE WAY DOWN TO LAKE OKEECHOBEE AND
SOME GUIDANCE SUGGESTS IT MAY DROP SOUTH OF THE LAKE BY THE END OF
THE DAY. TEMPERATURES CONTINUE TO PLUMMET EARLY THIS MORNING AND LOW
TEMPS WILL BOTTOM OUT IN THE MID TO UPPER 20S AROUND THE LAKE AND
LOWER 30S ACROSS THE METRO AREAS. THE TEMPERATURES WILL FEEL EVEN
COLDER THOUGH THANKS TO A TIGHT PRESSURE GRADIENT BETWEEN THE
QUICKLY DEEPENING LOW OFF THE MID ATLANTIC COAST AND STRONG HIGH
PRESSURE OVER THE SOUTHERN US. WIND GUSTS OF 40-45 MPH ARE EXPECTED
THROUGH DAYBREAK, WHICH WILL RESULT IN DANGEROUS APPARENT TEMPS IN
THE TEENS AROUND THE LAKE REGION AND 20S OVER THE REST OF SOUTH FL.
AS FOR CURRENT HEADLINES, WE HAVE EXTREME COLD WARNING AND FREEZE
WARNINGS FOR GLADES, HENDRY, AND PALM BEACH. FREEZE WARNINGS AND
COLD WEATHER ADVISORIES FOR METRO/INLAND BROWARD, METRO/INLAND MIAMI-
DADE, AND INLAND COLLIER. COLD WEATHER ADVISORY FOR COASTAL BROWARD,
COASTAL MIAMI-DADE, COASTAL COLLIER, MAINLAND MONROE, AND FAR SOUTH
MIAMI-DADE. ALL OF THE COLD WEATHER PRODUCTS ARE IN EFFECT UNTIL 10
AM THIS MORNING. IN ADDITION, THE ENTIRE AREA IS UNDER A WIND
ADVISORY FOR WIND GUSTS UP TO 45 MPH UNTIL 7 AM.
DESPITE PLENTY OF SUNSHINE EXPECTED TODAY, TEMPERATURES WILL
STRUGGLE TO REBOUND AS THE COLD AIRMASS CONTINUES TO FILTER INTO THE
REGION. HIGH TEMPS WILL BARELY REACH 50 NORTH OF ALLIGATOR ALLEY,
AND WILL REACH THE LOW TO MID 50S OVER THE FAR SOUTHERN PENINSULA.
THE PRESSURE GRADIENT WILL START TO RELAX AS THE DAY PROGRESSES,
HOWEVER WIND GUSTS OF 20-30 MPH ARE STILL EXPECTED THROUGH SUNSET
TONIGHT.
TONIGHT WILL BE ANOTHER EXTREMELY COLD NIGHT ACROSS THE REGION. WITH
MAINLY CLEAR SKIES AND WINDS CONTINUING TO RELAX, TEMPERATURES WILL
PLUMMET QUICKLY TONIGHT AND MANY INLAND LOCATIONS WILL AGAIN FALL
BELOW FREEZING. LOW TEMPS WILL RANGE FROM THE MID TO UPPER 20S
AROUND THE LAKE, TO LOW AND MID 30S ACROSS THE METRO. WITH THE
LIGHTER WINDS IN PLACE, ESPECIALLY WEST OF THE LAKE, FROST WILL
BECOME MORE OF AN ISSUE TONIGHT. FROST MAY EVEN BE OBSERVED OVER
WESTERN PORTIONS OF THE METRO, ESPECIALLY IN SHELTERED LOCATIONS.
WHILE THE APPARENT TEMPS WON'T BE AS LOW TONIGHT, THEY WILL STILL
FALL INTO THE 20S OVER MOST OF SOUTH FL. COLD WEATHER HEADLINES WILL
BE ISSUED LATER TODAY AFTER THE CURRENT HEADLINES ARE EXPIRED.
WHILE DAYTIME TEMPERATURES ON MONDAY WILL BE "WARMER" THAN SUNDAY,
THEY WILL STILL REMAIN WELL BELOW NORMAL ONLY REACHING THE UPPER 50S
TO AROUND 60.
LONG TERM
(MONDAY NIGHT THROUGH SATURDAY)
ISSUED AT 106 AM EST SUN FEB 1 2026
AS HIGH PRESSURE SLOWLY SHIFTS OVER THE AREA ON TUESDAY AND
WEDNESDAY, WE'LL START A SLOW WARM UP ACROSS SOUTH FL. COLD WEATHER
HEADLINES WILL LIKELY BE NEEDED AGAIN TUESDAY MORNING ESPECIALLY
OVER INLAND SOUTH FL WHERE LOWS WILL BE IN THE LOW TO MID 30S. AS
THE HIGH SHIFTS EAST OF THE AREA MID WEEK, THE LOW LEVEL WINDS WILL
BECOME SOUTH TO SOUTHWESTERLY WHICH WILL BRING TEMPERATURES UP TO
NEAR NORMAL FOR WEDNESDAY. THIS WARMUP WILL BE SHORT-LIVED HOWEVER
AS ANOTHER COLD FRONT IS EXPECTED TO CROSS THE AREA ON THURSDAY, AND
THIS WILL REINFORCE COOLER AIR INTO THE REGION FOR THE REMAINDER OF
THE WEEK AND INTO AT LEAST THE FIRST HALF OF NEXT WEEKEND. THE ONLY
REAL RAINFALL CHANCES IN THE EXTENDED PERIOD WILL BE LATE WEDNESDAY
INTO EARLY THURSDAY AHEAD OF THE APPROACHING FRONT, HOWEVER QPF
VALUES APPEAR TO BE A TENTH OF AN INCH OR LESS SO THERE WILL BE
LITTLE TO NO RELIEF FOR THE ONGOING DROUGHT.
TEMPERATURES OVERALL THIS UPCOMING WEEK WILL REMAIN BELOW NORMAL.
BESIDES TUESDAY MORNING AS MENTIONED ABOVE, THE ONLY OTHER DAY THIS
WEEK WITH POTENTIAL COLD WEATHER HEADLINES WILL BE FRIDAY MORNING,
AND THAT MAY JUST END UP BEING OVER INLAND SW FL.
